ItIACHIE-TE FOR- COlTFOR-MING UPPERS TO LASTS.

Application filed November fl, 1328, Serial No. 146,264,

This invention relates to machines for use in the manufacture of shoes for conforming uppers to the shape of their lasts, and has for one of its principal objects to provide in upper-conforming machines or" the pulling-over machine type improvements relating to operations upon' the upper farther rearwardly than has been the practi e heretofore in the use of pulling-over machines,for example, in locations where the edge of the shoe bottom curves inwardly toward the shank at the rear of the ball line.

It is the usual practice in the manufacture of most of the well-known types of shoes to subject the upper, after the pulling-over operation and prior to the side-lastingor" the shoe, to an operation known as waist-pulling, whereby the upper is pulled and fastened to the insole in locations considerably at the rear of those where the side grippers of the pullin ovor machine engage it, usually just at the roar of the ball line where the edge of the shoe bottom curves inwardly toward the shank. This operation is regarded as desirable, especially on high-class work, in order to guard against the accumulation at any point of undue fullness in the upper, with consequent wrinkling, when the side-lasting r ion is performed by the use of a lasting no of the step-by-step type, and also to assist in conforming the upper tightly and smoothly to the contour of the last over the instep and in the shank. This separate waistpulling operation is'usually performed manually by the. use of hand pincers, first at one side or-E the shoe and then at the other side, although under some conditions it may be performed by the use of the side lasting machine before the machine is used in the custernary manner to last the shoe progressively along the sides.

It is an object of this invention to provide means for performing the waist-pulling operation in the pulling-m 'er machine, thus eliminatin the necessity tor a so; arate waistpulling operation between pullingver and closed a novel organization of means for pulling an upper over the forepart of a last and for pulling it also and fastening it adjacent to the ends of the ball line, substantially in the locations where the edge of he shoe bottom curves inwardly toward the shank. It considered preferable that the pull near the 'Ihere is accordingly herein dis and in Great Britain November 24, 1825.

ends of the ball line shall not take place until after the upper has been pulled at the forepart, and the invention accordingly provides an organization whereby the different upperpulling operations are automatically timed to take place in this sequence.

In accordance with a further very desirable feature of the invention, the operator of the pulling-over machine is relieved of the necessity of exercising more care or of spending more time than customary in presenting the work to the machine and arranging the upper in the gripper jaws, notwithstanding the addition to the machine of the waist-pulling grippers. To this end, advantage is taken of the fact that the waist-pulling grippers, as above explained, do not apply their pull to the upper until after the upper has been tensioned by the main pulling-over grippers, the waist-pulling grippers being so arranged that the margin of the upper is introduced between their open jaws by the pull of the main side grippers. In the construction shown, moreover, the waist-pulling grippers are so mounted as to be yieldingly movable heightwise of the shoe in response to engagement of the margin of the upper therewith as the upper is pulled by the main grippers, so that before they operate upon the upper they assume positions determined by the extent of the pull first applied at the forepart.

When'tho waist-pulling operation is performed in the pulling-over machine, it is found that the stretching of the upper etlected by the main grippers in their updraw movement (i. e., their movement heightwise of the last) is such that it is sufficient for the waist-pulling grippers to operate with Q overdraw movements only, thereby simply pulling the upper inwardly Over the insole and laying it thereon in position to be tastened. The invention, therefore, further provides ion impartingto the waist-pulling grippers, as distinguished from the main grippers, movements only in directions generally .'idthwise of the last. Conveniently also, the waist-pulling grippers may be so constructed and arranged as to extend generally idthwise of the last, while the main grippers extend, as usual, in directions substantially h htwise of the last. In the construction in shown, moreover, the waist-pulling grippers are so mounted that, asthey are moved inwardly over-the bottom of the last, they are permitted to approach the plane of the last bottom in response to resistance of the upper to the inward pull of the grippers thereon, so that they lay the margin of the upper upon the bottom face of the insole; and provision is afforded also for turning movement of the gripper jaws into positions approximately parallel to adjacent portions of the edge of the shoe bottom at the rear of the ball line simultaneously with their inward pulling movement, to assist in laying the upper evenly over the edge of the insole. Preferably, as shown the means for moving these grippers inwardly over the insole is yieldable in response to resistance of the upper when the upper has been subjected to a predetermined stress, sothat-the grippers assume positions determined by the particular shoe .in accordance with the stress of the upper.

Theinventionfurther provides novel means for fasteningthe upper in the waist-pulling locations. comprising fastening devices that are positioned relatively to the shoe by the movement of the grippers, the construction shown comprising tack-driving devices that are carried by the grippers. In order to insure that the fastening devices will be properly effective to fasten the upper, the grippers herein shown, while yieldable toward the plane of theshoe bottom as above explained, are locked against yield in the opposite direction at the time of the fastening operation. It will be evident that, with the grippers positioned relatively to the shoe in accordance with the stress of the upper, as above described,the fastening devices are likewise so positioned; and in one form of the invention the fastening means is rendered operative to drive the fastening in response to resistance of the. upper to the inward movement of the gripper.

\Vhile the invention thus has principally in view improvements relating to what is termed a waist-pulling operation, it is considered that in the provision of upper-pulling and fastening means such as disclosed the invention presents various novel and useful features irrespectivc of the particular location uponthe shoe where the operation in question is performed, and it is the intention to claim the invention thus broadly. The invention is illustrated, by way of example, in its application to a well-known type of pulling-over machine the characteristic features of which are shown and described in United States Letters Patent No. 1,510,851, granted on October 7, 1924, upon an application of Arthur E. Jerrain and Joseph Gouldbourn, and in earlier Letters Patent therein mentioned; but it is to be understood that it is not limited to machines of that particular type.

The'above-mentioned and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In the drawings,

Figs. 10 and 11 are views further illustrating, with reference to a shoe, different operating positions of the waist-pulling grippers.

As fully shown and described in the abovementioned Letters Patent, the pulling-over machine illustrated comprises in its general organization a toe gripper B and opposite side grippers C (Fig. 1) which are operated to pullan upper over a last positioned bottom downward upon a sole rest 1). It. will be understood that these grippers, which engage the upper at the end of the and at the sides of the forepartat or n ar the ends of the. tip seam, are operated automatically by leouendriven means to grip and pull the upper heightwise of the last upon the starting of the machine, and that the machine then comes to a stop with the upper held under tension. Nhen the machine is again started the grippers are operated to draw the upper inwardly over the insole and the margii'i of the upper also is wiped inwardly over the insole and is fastened by tacks driven upwardly through the upper and into the insoie at the end of the toe and the sides of the fore part.v Portions of the overwiping and fustenin devices are shown at For purposes of the present invention there is provided at each side of the machine, at the rear of the side grippers C, a waist-pulling gripper for pulling the upper at or near the end of the hall line, preferably at that portion of the shoe where the edge of the shoe bottom curves inwardly toward the shank, together with means for fastening the upper in that location. The drawings show in detail the waist-pulling mechanism at the left-hand side only of the machine. stint-e, it will he understood that the corresponding mechanism at the other ide of the machine will he simi larly constructed and arranged. This waistpulling mechanism, indica ed generally at F (Fig. l). is mounted indirectly, as will more fully appear. upon a bracket ll whieh is pivoted upon a stud l?) 1 the ram-' of the head of the maehine so that lay adjusting the hracket ahout the stud the position of the mechanism lengthwise ot the shoe may he varied. The lira *ltet 11 is provided on one side, with a hut 15 (Fig. 2) which underlies a retaining plate 1? that acts both to prevent the hrarltet from springing: outwardly. widthwise of the shoe. and also to clamp "he hra ltet in adjusted pordtion. l't' ltvall'tFil, the hracliet may he further gu' led and held hy simi means (not shown) located on the opposite side thereof from the lug l5. Any shitahle means also may he provided. it desired. for adjusting the brackets 11 at the opposite sides oi" the machine, either simultaneously or he dividually, to position the opposite waist.- pultine mechanisms ditl'erently tor operat1 inej upon right and let't shoes.

Mounted on the hrarliet ll is a ti gripper-supportinghracket ll (Figs. 2 provided on one side with a pivot: which tits in a hole formed in an extension 21 of the bracket 1] and an arcuate rih on the bracket, 41, concentrie with the hol -e. u :derlies a corresponding rih on the lil'tltlflti it and assists in guiding the hrarltet ll as t moves about the axis of the pivot stud lil. The axis oi the stud ll extends ,sg'eneraliy parallel to the longitudinal median time the shoe.

n s ring to sepaalso have a short rocking: movement relatively to the bracket 11 about the axis of ta;

pivot stud 43 to permit the gripper to ssurne different positions heightwise of the shoe.

On the opposite side oi the tlmztin g,- hracltet 41 from the pivot stud 43 there is formed a rectangular slideway (Fig. in which is mounted a gripper jaw carrier 51 formed with a shoulder 53 (Figs. 4 and 5) for engagement 'ith a shoulder on the floating;- hracltet to limit outward movement of the jaw carrier away from the shoe. In order to assist the slideway in holding the jaw carrier 51 from springing downwardly in the operation ot the fastening: means (hereinafter descritrcd}, the floating hraeltet ll provided with a projection 55 (Fig. which underlies that portion of the jaw carrier 51 which projects outside of the slidewaj.

The inner end of the jaw carrier 51 is bored to receive a pivot stud 57 depending from an inner jaw 59 of the Waist-pulling gripper. This jaw is provided with an outwardly extending: tail portion 60 which is held in place at its outer end by being located in a re' ess (S1 in the carrier 51. but is free to swing with the jaw 59 aliout the axis of the stud 5?. (o-operating, with the inner jaw 9 is an outer jaw 63 which has a depending rih (55 mounted for sliding movement in a parallol-sided slot extending lengthwise of the tail ()0 of the inner jaw, the arrangement being such that the outer jaw can slide toward and from the inner jaw upon the tail 60 but not laterally thereof. ln order to hold the outer jaw 63 slidahly in place, its rih 65 is fixed to a slide 67 whieh extends through a slot 69 (Fig. 4) in the jaw carrier 51 and is fastened to a cover plate 7]. underneath the jaw carrier. The slot 69 is formed that it not only permits the slide 67 and the outer jaw to move longitudinally of the carrier 51, or widthwise of the shoe. but? also permits ho'th aws to he swung with the tail 60 about the pivot 57, as will hereinafter more fully ap pear.

In order to provide for the operative movement ot the waist-pullinn ,e ripper jaws, the rarrier 51 is slotted longitudinally to form a uidewav or a jaw actuator 73 (Figs 2 and the inner end portion of which is arranged to cont'aet with a projection 75 on the outer jaw 63 and force the jaw inwardly towa d the jaw 59. The actuator 73 is provided with a shoulder Tet to engage the carrier 51 and therehy limit outward movement of the art uator away from the shoe.

The slideway for the carrier 51 in the l'rachet H is provided with a over 77 (Fig. 4) havinethereon :1 lug 79 on which is mount;- ed a 4,-arrier-holding pawl 81 arranged to enpage teeth 83 on the carrier 51 to hold the latter with the inner jaw 59 at times against: outria rd movement, the tail 85 of the pawl being on aged by a spring to hold the pawl in operative position. The pawl 81 has fixed thereon an offset arm 87 the end of which extends into the path of a member 89 which moves at the orrert time to lift the pawl from engagement with the teeth 83 and thus permit the inner jaw to move outwardly, the member 89 being a portion of the mechanism provided for transferring tacks to the side tacker arms, as more fully described in the Letters Patent mentioned. The arrangement is such that the inner jaw 59 is not released by the pawl until after the outer jaw 03 has been retracted from the inner jaw by the pull of a lug 76 on the actuator 73 upon the projection 75 ot' the outer jaw, and has thus released the upper.

The jaw actuator 73 carries a bent rod 91 which is connected by a tension spring 93 to a hook 95 on the jaw carrier 51. so that after the inward pulling or overdrawing of the upper by the waist-pulling gripper has been completed. and while the outer jaw (33 is being returned to its outer position. the spring 93 is tensioned by reason of the tact that the carrier 51 is held by the pawl 81 from being retracted. When the pawl 81 thereafter releases the carrier 51. the spring 03 serves to retract the carrier with its jaw 59 to the position determined by engagement of the shoulder 53 with the bracket 41. the jaw 59 being then spaced from the jaw 63 sutticiently to permit the margin of the upper of the next shoe to be introduced between the jaws. In order that the spacing ot the jaws may be varied. a stop 42 screwed into the bracket 11 and is adapted to Contact with the outer end ot the carrier 51. so that by adjusting the stop the carrier can be positioned with its shoulder 53 out of engagement with the bracket 41 and at different. distances therefrom. It will be understood that the spring 93 is always in tension, and in gripping the upper the stress of the spring is reduced as the outer jaw 03 is moved inwardly under control of the actuator 73 until the upper is gripped by the force of the spring, after which both jaws are moved inwardly to pull the upper by continued nmvement of the actuator 73 in engagen'ient with the outer jaw.

The actuator 73 operated to caus the \vaist-pulliniz gripper jaws to clo e upon the upper and to pull he upper inwardly over the insole by connection with the means whereby. atter the pulling o t the upper by the main grippers it and inward movement toward the shoe is imparted to the usual side tacker arms ol' the pulling-over machine. which carry the means. indicated g nerally at E {Fig 4). for wiping the upper inwardly and for fastening it by the use of tacks. This means includes he u ual side trip spring casing 101 (Fig. ill, which receives operative movement. at the beginning of the second stage of the cycle of the machine, from mechanism of the well-known type illustrated and yieldingly connected in a well-known manner 'ith one of the side tacker arms, a portion of which is shown at 102. The casing 101 is provided with an extension 103 having therein a slot 105 in which is located a roll 107 mounted on one arm of a bell-crank lever 109 pivoted on the frame of the machine. The other arm ot the lever 109 has rotatably mounted therein a shackle 111, pivoted in the forked end ot which is a block 1153, and through a hole in the block 113 extends one end of a rod 115 which is gripped bet ween two pins 117 cvtending through the block 113 and held toward the rod by a U-shaped spring 110. The other end ot the rod 115 is mounted to slide through a pin 121 which pivotally mounted in a shackle 1233 (Figs. 4 and the shackle 123 being pivoted in one arm of a bellcrank lever 125 carried by ti bracket 11. A. com n'ession spring 127 is mounted on the rod 115 between the bell-crank le -er 1 and a nut 12 on the rod to transmit movement of the hell-wank lever 100 to the lever Means indicated generally at are provided for :uljtuting the strength of the wring 121', so that there shall be no UYOFSii'Cl'tlllilf ot the upper.

grippers are open; and the arrangement is such that the margin of the upper is introduced into the waist-pulliinr grippers by the action of the main grippers, thus relieving the operator ot the necessity of giving any special attention to the wai t-pulliinr grippers in present ing the work to the machine. As hereinbctore de cribed. the bracket 41 may swing about the axis of the pivot stud 13 against the resistance of the spring: 45, to cause the waist-pulling gripper ja ws and (33 to move downwardly in a directitm away from the shoe bottom. Such movement of the jaws will take place in IQSPODHP to engagement of the margin ot the upper with the tail (it) of the inner jaw 59 when the upp r is pulled by the main pulling-over grippers B and (l before the waist-pulling gri 'ipers are clo ed thereon. in their initial positions the waistpnltina' gz rippers are located below the margin ot the upper, but at a higher level than that to which the margin will be pulled by the action of the main pulling-over grippers. The taut. edge ot' the upper wil there'l'ore, enter the open waist-pulling gripper jaws and will swing the jaws downwardly to positions (ltermined bv the extent of the main pull 'ot the side grippers, so that the waistaiilii'u, grippers will be automati a iv adjusted to the correct heigg'htvh e posi ion for subsciguently gripping the upper.

it is des rable that at'ter the waistmulling grippers have been correctlv adjusted to the proper hcigi'htwise position by the action of he margin of the upper thereon, they shall be restrained from subr'iequent movement in a direction awav from the plane of the shoe bottom, especially when the fastening mechanism associat d therewith is operated to l'asten the upper in the manner hereina l ter drscrihed. has

Accordinglv the bracket 4-1 pivoted thereon a pawl 141 (Fig. which pressed h a spring 143 into minagement with t th 145 formed on a block 147 iixed to a wing: extending from the bracket 11. The pawl lt-l rarries an extension 149 arransred to be ou raged bv the nose 131 of the pin 12!, rothal when the hell-crank lever 125 is rocked to close the jaws and move them inwardly over the shoe bottom, it releases the pawl 14.1 tor engagement with the teeth 1-15 so as to lock the bracket 41 from downward rocking? movement. The pawl. however, does not prcvent the waist-puitin;; gripper troni moving up tmvard the shoe hottom as it is operated to pull the upper inwardly over the insole, and such movement will ordinarily take place in response to the pull oi the upper thereon, so that the gripper will act to lay the upper upon the bottom tare ot the inside. lVhen the hell-crank lever 125 is moved in the opposit direction, the nose 131 strikes the extension 145) of the pawi 14- and disennagres the pawl from the teeth 145. For greater pre cision the pawl 141 is dupiicated, the seconr'i tooth-engaging edge being half a tooth in front of the first.

It will be understood that each of the waistpulling grippers will be initially adjusted into proper position to receive the margin of the upper by manipulation of the nuts 48 and by adjustment of its supporting bracket 11 about the pivot 13. The jaws of. each waist-pulling gripper are, moreover, initially very much wider apart than the main gripper jaws, in order to insure that the margin of the upper will be pulled into position between them by the action of the main jaws.

For fastening the upper after it has been pulled by each waist-pulling gripper, there are mounted on the movable cover plate 71 under the jaw carrier 51 two cars, one of which is shown at 151, having therein slots 153 which provide a guideway tor a driver bar carrier 155 to which is secured a tack driver 157. The driver 157 is arranged to operate in an oritice or tack pocket 159 formed in the outer jaw 63 to which a tack is delivered from al We by mechanism not herein shown but similar to that provided for delivering tat-ks to the main tacking devices. For operating; the driver 157, a toggle arm [61 is pivoted to the ears 151, another toggle arm 163 is pivoted to the driver bar carrier 155. and the two toggle arms are pivoted together on a pivot member 165. The toggle arn'is are mounted between the ears 151 and are con venicntlv composed of duplicate links. The pivot member 165 has a shank provided with a quick thread for engagement with a ball-ended nut 1G7 held in a spherical socket formed in the ears 151, so that when the nut s turned in one direction the toggle is traightened and the driver 157 operated to lrive a tack, and when it is turned in the pposite direction the driver is retracted. l he nut 167 has a. socket in which is tixed one end of a flexible shat't 171 (Fig. 1). it will thus be evident that the tack drive' and its operating connections to the flexible shaft 17] move with the jaw (13 toward and from the jaw 59 and also swing with the -s about the axis of the stud. 57. so that the location of the tack is determined by the position oi the gri pper.

For rotating the flexible shaft 171, first in one direction and then in the other, it. is connected to illtt'l t ism with which machines ot the illu.--:trat iv: tvpe are provided for retracting; or rocking the main driver bars after the driving; ot the pulling-over tacks. t will be understood that this well-known mechanism. a portion of which shown in Fig. 3, is piv oted at 175 on the frame of the machine for operative 5-;winging movement, and comprises at each side of the machine a driver bar rera ctingg' plate (not shown For the purposes in view. there pivoted also at 175 a bent lever 173, the upper end of which is secured at 177 to a portion of the above-mentioned driver bar retracting mechanism, preferably to the driver bar retracting plate located at the same side of the machine. The other end of the lever 173 is pivoted to a, rod 179 having: rack teeth 181 t'orn'ied thereon which engage grea r teeth 1853 cut in the shaft 18:). The rod 179 is slid-ably mounted in a cas ng: 187 which is pivoted on the shaft 185. The einl ot' the shaft 185 fixed to the lower end of the flexible shaft 171. and when the above-mew tioned driver bar plate is swung upwari'llv about its pivot 1T5 preparatory to the lowering or retractin ot the main driver bars. the flexible shaft 141 rotated in one direction to operate the driver bar carrier 153 of the waist-pulling mechanism. 'hen the plate receive its downward movement to retrac the driver bars. the flexible shaft is turned in the opposite direction to retract the carrier It will thus be seen that the tacks for fastening the upper in the .vaisbpulling locations are not driven until at'ter the main pulling-over tacks have been driven. but preferably before the shoe is released by the is'ieans (not shown) which supports it against the pressure ot the tack drivers.

In order to provide for the introduction of the hereinbefore described waist-pulling; mechanism into the machine. the usual tipst raightening mechanism is removed and the support of the shoe rest D is somewhat altered in shape to provide suitable clearance for the additional qrippers. Any convenient construction of tip-straightening mechanism may be used, in a different position. in place of that removed; for example one such is disclosed in Letters Patent Jo. 1.6563535. granted on January 17. 1928 upon an application of Robert H. Silvester and Arthur Rates.

The waist-pulling mechanism at the opposite side of the macl'iine, including the gripper and the fastening means. will preferably be identical with that herein described. except for such constructional alterations as may be necessary to adapt it to the different position in the machine. There will. however. be no need of duplicatingthe mechanism for rotating the tack-driving shat't 185. since that shaft may extend to both sides of the machine and may have a flexible shaft 171 coupled to each end of it.

In the operation of the machine. after the opposite waist-pulling mechanisms have been adjusted in the manner described to position them in proper relation to the size and style of shoe on which the machine is to operate. and it may be also to adapt them to the particular requirements of a right or a left shoe. the operator presents the shoe, to the machine in the usual manner, positioning the margin of the upper within the main pulling-over gripper jaws l3 and C without giving any particular attention to the relation of the up per to the waist-pulling gripper jaws. The

machine is then started, and the main grippers are operated to tension the upper at the end of the toe and the sides of the forepart, whereupon the machine comes automatically to a stop. In this operation the margin of the upper, as it pulled downwardly by the grippers, engages the tail 60 of each of the inner waist-pulling gripper jaws and thus 'oclts both the waist-pulling grippers downwardly to position them in accordance with the extent of the pull applied to the upper at the sides of the shoe. lVhile the machine is at rest after thus pulling the upper, the operator is enabled to straighten the tip as may be required, before the waist-pulling grippers have gripped the upper. by manipulation of the tip-straightening mechanism in the well-known manner. In the next or final stage of the cycle of the machine at the, time when the side tacker arms 102 are swung inwardly toward the shoe to lay the margin of the upper over the insole, the bellcrank levers 125 are operated in the manner described to close the waist-pulling gripper jaws upon the upper and to cause these grippers to pull the upper inwardly over the insole. By the movement ot the bell-crank levers 125 the pawls 141 are released to permit them to loclt the waist-pulling grippers from movement away from the plane of the shoe bottom; and at this time also the carrier-holding pawls 81 are in engagement with the teeth 1 3 on the jaw carriers, so that as the latter are moved inwardly they will be locked in their innermost positions. During the inward movements of the waist-pulling grippers they will rock about the pivot studs 4-3 of the floating brackets 41 in response to the pull of the upper upon the gripper jaws. so that the jaws will approach the plane of the insole and will lay the upper upon the bottom face. of the insole. illustrated in Fig. 11. T e jaws will a so be wlliigg' about their pivots 57 by the action of the actuators 72 thereon in the manner hereinbefore described, so that they wi l twist the margin of the upper and will a eanne positions more nearly parallel relation to the adjacent portion of the edge of the shoe bottom where the edge curves inwa dly toward the shank. The springs 12? will, as a rule. yield to prevent the upper from be over-stretched, and it necessary the tric n grip of the pins 117 on the rods 1 15 will also yield.

After the upper has thus been pulled inwardly by the inst-pulling grippers. and also ai'ter the main pulling-over tacks have been driven. the tacks in the waist-pulling locations are driven in the n'ianner hereinbei ore describml. Thereafter the return moven'ients of the trip-spring casings 101 wi l t r-at retrhe on 'nmst-nullin or i i i d l *M "2 per ws to release the 'i ier. the inner jaws being ,illl held by the pawls 81. In the return moven'ient oi" the bell-crank levers 125 the pawls 141 are retracted, thereby releasing the waist-pulling grippers for downward movement in operating upon the next shoe. Near the end of the cycle the carrier-holding pawls 81 may likewise be retracted from the teeth 83 to permit the inner aws to be moved outwardly by the springs 93, or by a suitable arraiu 'ement of means for operating the arms 87 ot the pawls this action may be delayed until in a. new cycle of operations the tensioning of the upper by the main pulling-over grippers has at least begun.

it it is not desired that the waist-pulling 11 I as be swung to cause their upper-grip nine l'acrs to assume posi ions approximate- .v parall l to the adjacent. edge of the shoe bottom, an (H 1l':.iliI4 ion somewhat more simpl than that lwrcinbet'ore described may be util'zed. and such an organization is shown in is. 6 to t). inclusive. The waist-pulling new; .nism of the alternative construction is mounted indirectly upon a luacket 211 similar to the bracket 11 ot the construction first d scribedandsimiiarlyadjustable. iitloatin g' bracket 241 is provided one one side with a pivot stud 213 (correspon, in to the stud 43 ot the construction first described) which is mounted to turn in a hole in the bracket 211. On the opposite side of the bra ket 241 from stud 242} there is formed a rectangiu lar siadeway in which is mounted for longitlgtlltlz l movement an inner jaw carrier 2.31 havine; at its inner end a jaw 253 and at its outer end a shoulder arranged to contact with an adjustab e screw stop 245 on the bracket 5331. so that this stop limits the outward movement of the inner jaw. The inner end portion ot the iaw carrier 1251. which projects tron;

the pivot the lt-racl-tet 2.411. is provided with a slot 269 tl. which there pro ects a rib forming a tion oi an outer jaw 261. a cap plate 263 b ing attached to the rib in order that the outer jaw mav be kept in place on the inner iaw carrier in its s iding movement toward mud fr m the inner jaw.

For moving: the outer jaw 261 toward and m the inner jaw F2533. and for moving both is ws widthwise oi" the shoe to pull the upper. there is provided a jaw actuator 273 which i heated. with the inner jaw carrier. in the ioctanp'ular slidcway in the floating bracket ixll and can slide longitudinally therein. Th inner end of the actuator 27?; provided with a hook 275 which engages a hook on the outer jaw 261. The outer end ot the :u'ztuator 273 is provided with a guideway 277 (Fig. 9) in which is located a slide 2T9 noruir'illy held from moving relativelv to the actuator. one end of the slide 97.) having a. lateral extension 291 (Fig. 8) projecting through a slot in the side of the actuatm'. The extension 281 carries a sphrri cally-siu'i'aced pin 283 connected bv a link to one end. of a bell-crank lever 28'? which is mounted and operated similarly to the bell-crank lover 125 of the construction first described. with the exception that there is no provision "for yield in the operating connections.

In order that there shall be no over-stretcl'iing of the upper. the slide 279 is adapted to move relatively to the actuator 273 along the guide av 277 when the upper has been subjected to a predtjstermined degree of tension. The actuator 273 carries :1 lug 280 and a wing: 282. both of which members extend through slots in the inner jaw carrier 251 and the floating bracket 9A1. Mounted in the wing f2 2 is a poppet or plunger 28% having a beveled end adapted to enter a coniplemcntallv shaped recess in the slide 279 so norinally to hold the slide stationary relatively to the actuator 5273. Pivotally mounted on the lug it) is a driver arm 291 haviu; fast thereon a second arm 20?) to which is pivoted one end of a bar 295 that is pivoted at its other enil to a rod 297 extending upwardly through the actuator 273. The rod 297 carries a semi-spherical washer 299 seated in a re-i'css in the a iuator 273 and held thereagainst by a spring 301 the tension or which may be adjusted by a nut 30? on the rod 29?. The bar 295 engages the outer end of the plunger 28 and thereby holds the latter yit-lt'line ly in ci'rgae ement with the slide 279 as illustrated in Fig. 9.

The driver arm 291 carries a driver and when the driver is cocked. or in retracted position. a shoulder 805 on the bar 295 is in engagement with a enumerating lip 30? on the wine so that the ba 295 acts as a latch to hold the driver retracted. lVhen the bellwank lever has moved the jaw actuator 2T3 to grip and to stretch the upper with the required force. further movement ot the lever 28? causes thc slide 279 to move relatively to the actuator 273 by reason of resist ance ot the upper to further inward movement o1 the gripper. the beveled face of the plunger E284- slidine; upon the sloping face of the recess in the slide 5379. This rauscs the phing r o saving the bar 295 sufiicientlv to release the shoulder Eltlfl from the lip 307. whereupon a spring 2309 located between the wine. and the arm 293 swings the latter about its pivot and causes the driver 292 to drive a tack. The driver passes through the outer jaw 2G1 and adjacent parts by means of openings that are tapered to allow for the anfzularity of the driver movement.

In order to cock the driver 292. the driver arm 291 carries a third arm 311 which, when the bell-crank lever 28? retracts the jaw actuator 273. is carried into engagement witlran adjustable stop 313 on the bracket 24]. and the driver arm is thereby turned until the shoulder 305 on the bar 5295 passes the lip S07. whereupon the shoulder is pulled by the sprint 301 into position behind the lip. ln the driving movement of the driver 292 the ltlt) lltl arm 311 is arranged to contact with a step 312 on the actuator 273 to limit its movement.

A pawl 34-1 on the bracket 241 co-operates with teeth on a block 347 on the bra iket 211 in a manner similar to the operation of the corresponding parts 141 and i l? of the con struction tirsz described. A carrier-holsling pawl 381 also acts similarly to the neviously described pawl 81 to hold the inner iaw 5253 in its innermost position against the tension of a spring (not shown but similar in action to the spring 93).
